Hi Jon, Ah, sorry. Now I understand your question. :) The brownish one can be a male. This fish has very well full-blown odontodes at the head-sides, so what I can see. Females just have a few (if they have it). The other with the strong contrast in coloration I cannot see any odontodes. The picture...

Hi Jon, Sorry I dont understand your question completely. Would you like to know the sexual differences ? The most important difference are the odontodes of male Sturisoma at the sides of their heads. Some species did have this difference just at the spawning season. For example S.aureum . Attention...

Hi Jon, You saying these are actually of festivum? No, i said mostly. Especially the first one can be S.aureum . The fin are schmal and straight and the body has fine drawing all over. This characteristics are typical for S.aurum . The second one could be a S.festivum with a very nice pattern. The f...

Hi Jon, Your S.panamense isn't one. Here is a real S.panamense . This is the one and only photo in the cat-e-log of an aldult wich shows a S.panamense : http://www.planetcatfish.com/images/full/loricariidae/sturisoma/panamense/1.jpg All the others mostly shows S.festivum . I think both of your Sturi...

Hi Janne, I agree with Shane and say that your Sturisoma isn't S.festivum . The shape and the color of the dorsal fin doesn't match with S.festivum . even a little more brownish in colour compared to my females This difference i've also with my Sturisoma festivum and Sturisomatichthys cf. tamanae . ...

Hi Janne,

You aren't right. The hook at the end of the dorsal fin isn't a sexual difference.
What i mean is the typical S-Form of the dorsal fin. Only S.festivum has this shape. You can see it better in the glas-mirror at the right of this fish.

Norman

Hi,

In my opinion this Sturisoma is S.festivum. The shape of the dorsal fin is typical for this species.

Hello Jorge,

I don't think so, that this whiptail is H.eigenmanni. This species hasnt this fine drawing like the whiptail on the photos. I think it could be a female H.wolfei.

greets
Norman

Hi CatBrat,

Good News !

I think your whiptail is a dark type of Hemiloricaria lanceoalta. So the dorsal fin looks like.

see you
Norman

Hi, I am sure your whiptail catfish is a species of the genus Hemiloricaria . It could be H.eigenmanni or a similar species. I always use Artemia to feed young Hemiloricaria for the first few days. Later on I take Cyclops Eeze und pulverized pellets. Some species want to have some herbal food. Look ...

Hi Allan,

No, your fish isn't the same as Peters.
I think it could be LG6 oder maybe H.castroi.
Do you know where they set down their eggs ?

Norman

Hi Allan, But he sold them all on as Rineloricaria microlepidogaster. The genus Rineloricaria was splitted in 2002 into 4 genera. The most species are now in the genus Hemilocaria . Some species stayed in Rineloricaria . The other both gerna are Leliella and Fonchiichthys with just a small number of...

Hi Allan, Look at Rineloloricaria -species like R.latirostris or R.sp.columbia . This species look a bit stout and the males have all over their frontbody many odontodes on no specific place. The shape of Hemiloricaria -species is an other. They are thinner and the odotodes are on the headsites, the...

Hi,

Of course it is a Hemiloricaria-species.
Peter, can you tell us the length of your fishes ?
H.beni reach just a size of 8cm.

Norman

Hi, I think it is a very nice looking Sturisomatichthys ! I think you can see it in the position and the size of the eyes. An other point is the nearly straight line between rostrum and dorsal fin. Sturisoma -species has a upturned rostrum if you are fowllowing the line. Also the position of the dor...
